So far I'm at 3 1/2 weeks into my renewal. I know that they cashed my check so it's just a matter of time.

You cant use the check cashing as any kind of a timing tool as the first place the renewal goes to is the bank folks, Since three weeks plus a little seems to be the consensus, if you haven't seen it by four to five weeks I'd call the folks in WV who handle the renewals. One time I waited the six or eight weeks before I called to find out they couldn't find it. They were real nice about it and got me one in 4 days after the call.
